Barack Obama is running a the first major party canidate to be black. Is this true? Simple answer no. Barack Obama is 50% caucasian, 43.75% arab, and 6.25% black. The amount of lineage or percentage of black ancestors has been disputed in past presidents including Jackson and Lincoln. There is one past president Harding whose black ancestors make up a larger percentage of blood then Obama’s. So the truth is we would be electing probably the 6th or 7th black president. I do believe however that he is the first true arab presidential canidate.
